Re: [Fwd: Having an expression in an set tag]

You can use the <c:url> JSTL tag

eg something like this...

<c:url var="link" value="${request.getRequestURL()}">
    <c:param name="nodeclicked" value="${NODEID}"/>
    <c:param name="firstChild" value="true"/>
</c:url>

Hi All,

       I used to construct a link as follows

<%
String link = request.getRequestURL() + "?nodeclicked=" + NODEID + 
"&firstChild=true";
%>

       I want to replace this with the set tag. I tried it as follows

*<c:set var="link" value="${request.requestURL + '?nodeClicked=' + 
NODEID + '&firstChild=true'}"/>*

    but this is not working. I am getting the following an error

An exception occured trying to convert String "?nodeClicked" to type "java.lang.Double"

 Have i done anything wrong in writing the expression.

Thanks
